DEvVICE FOR TRANSPMITTING POWER.

SPECIFICATION forming part of Letters Patent No. 651,769, dated J' une 12, 1900.

l Application filed August Z2, 1899.

T all whom it may concern: Y

Be it known that I, ANTON A. PETERSON, a citizen of the United States, residing at Sundahl, in the county of Norman and State of Minnesota, have invented a new and useful Device for Transmitting Power, of which the following is aspecification.

This invention relates to devices for transmitting power, and is designed particularly for running threshing-machines. In running threshing-machines it is common to transfer the power and motion from the engine to the cylinder of the machine by a band running on the driving-pulley of the engine and on a pulley on the shaft of the cylinder of the Y threshing-machine or on a shaft geared thereto, and on account of the danger of fire being communicated from the fire-box or `smokestack of the engine to the straw the threshable distance from the engine, and the powertransmitting belt is therefore a long one and commonly consists of a band several inches in width. lvluch annoyance occurs by reason of the sagging of the belt and its liability to slip on the pulleys, as Well as by the belt being caught by the wind and thrown off the pulleys or so jerked and twisted as to interrupt a steady and reliable movement of the cylinder.

One object, therefore, of the present construction and arrangement is to provide a rope or cable drive for the class of machinery stated, including devices having adjustable features and meansifor preventing slipping of the rope or cable and also permitting it to be positively held in operative relation and also to afford means for arranging the engine at an angle to the end of the thresher without detracting in the least from the eectiveness of the power-transmitting devices.

Other objects and .advantages will be disclosed in the subjoined description and the novel features set out in the claims, and an embodiment of the preferred form of the improved devices is illustrated in the accompanying drawings and susceptible of changes in the proportions, size, form, and minor details of construction, which fullyfall within the purview of the invention, and in which- Figure 1 is a top plan view of apart of a threshing-machine and engine-frame, showserin No. 728,125. (No man.)

ing the improved devices applied thereto. Fig. 2 is a horizontal section through the devices applied to the cylinder-shaft and showing a sectional form of pulley. Fig. 3 is a top plan View of one of the sectional pulleys partially broken away. Fig. t is a detail perspective view of one of the pulleys. Fig. 5 is a face-section through a portion of the improved4 drive-wheel. Fig. 6 is a transverse vertical section of a partof the improved drive-wheel. Fig. 7is an elevation of a part of the threshing-machine and support for the drive-wheel, showing the improved devices Similar numerals of reference are employed to indicate corresponding parts in the 'several views.

ing-machine is usually stationed at consider- I chine of any preferred form and which will have the usual necessary appurtenances, in-v The numeral l designates a threshing-macluding a cylinder and concave and a cylin- The improved devices, as before intimitting power from an engine, though they vare equally well adapted for use in connection with other power-generating mediums.

In the drawings, however, a part of an engine-frame 3 is shown, which gives bearing to a drive-shaft 4, and on the latter is fixedto rotate therewith the improved form of drive-wheel 5. This drive-wheel structurally `includesa central body 6, of suitablematerial, on the periphery of which are fastened a series of grooved ring-sections '7, Whichare held in place against slipping and disconnection from the body 6 by keys 8, fast on the said body and interposed between contiguous ends of the'said sections 7 and are secured by adhesive material or anysuit-able interposed fastenings. The keys 8 are grooved similarly to the sections 7, and by this means a body 6 of inferior material may be caused to practically serve the purpose in conjunction with a surrounding ring or bearing-surface of superior material. The sections 7 at points intermediate the ends have yielding grips 9 projecting outwardly therefrom and consisting, essentially, of U-shaped platesprings having their ends flared and bent IOO down or inwardly and adapted to receive .th'e rope or cable 1 0 ,and prevent slipping of the same on the .drive-wheel or disengagement `from the latter.

On the cylinder-shaft 2 pulley-sections 1l and 12 are adjustably mountedand have their inner opposing or vadjacent-ly-situated peripheral corners cut out a preferred depth to provide angular grooves'13. These grooves 13 unitedly form a space for the reception of the rope or cable lO. Each of the sections 11 and V12 has a bore 14- eXt-endingxthere-l, through and of a diameter considerably in excess of that'of the shaft 2, andprojecting outwardly from the face of each section op!" posite lthat in which the grooves 13 are formed are a'pair of parallel arms 15, pivotally connected to diametrically-opposite portions'o'f heads 1G, which have set-screws 17 extending therethrough in planes at right angles to the points of attachment. of the'saidj armste adjustably hold the'sections on the "-cylinder-shaft. By the pivotal connection of the arms 15 to the heads 16 thepulley-sections are allowed tomove inward and outwardk to and from the shaft as far as the dimensions of the bores '14 will permit. Inarranging the rope or cable 10 in connec.

tion with the improved'deviccs it is first run around the drive-wheel 5 and the opposite portions brought to bear against directionpulleys 1.8, which may be arranged in horiv,zontal planes, .as 'shown by Fig. 1, with the upper faces parallel orin the same plane, or,

" by transmitted to the cylinder-shaft 2 through the medium of said sectional` pulley. The

as .illustrated by Fig. '7,sa`id pulleys can be disposed. one-above the other, and in either instancel are held on suitable supports. The

jrope or lcable isthen applied to the space between the contiguous portions of t'hepullcys, 1-1' and .12 formed by the grooves 13, and as v thedrive-'wheel is rotated the rope or cable isjcorre'sp'ondingly actuated and power theremovement of the sections 11 Vand 12 inward toward or outward from thenshaft 2 will occur'automatically and to a degree proportionate to the tension or drag of the rope or cable thereon. By this means the shaft 2 is adapted to receiverope or cable belts of various gage.- Themovement'of the pulley-sections will not cause a wear on the shaft 2, asthe innerfaces of the said sections will be so close together that it will be impossible for the inner portions of the said sections to touch the said shaft. Slipping of therope or cable on the pulley-sections will be prevented by the adjustment set-forth, in view of thefact that at the point of the greatest pressure 'of :the rope or cable said sections will be pulled to reduce thespace normally established by the grooves 13. This will contract the rope or cable groove and Vcause the opposite'walls of the latter to come closerto the rope or cable. The

gle relatively to 'the threshing-machine, as clearly indicated in the drawings. ,tive operation arising from the use ofthe im- The posiproved attach-ment is o f material importance, and the simplicity of construction, together ywith the advantages accruing therefrom, lmakes the improvement of valuable acquisition to the art to which itr pertains.

Having thus described the invention, what ,is claimed as new is- 1. In adevice of the character set forth, the

combination with a shaft, of heads thereon 'spaced apart from each other, and pulleysections pivotally attached to said heads.

2. In a device of the character set forth, the

.combination with ra shaft, of heads thereon spaced apart from each other, and pulley- :sections pivotally attached to said heads and having inner grooved corners which initially form a receptive space for a rope or cable, :and openings therethrough of a greater di- 'ameter than that of the shaft.

3. In a device of the characterset forth, the

combination with a shaft, of opposi'tely-disposed heads adjustably .fixed thereto, and

grooved pulley-sections having arms pivot- ;a-lly connected to'said heads.

4. In a device of the character set forth, .the

Qcombination with. a shaft, of freely-movable pulleysections thereon having openings therethroughof greaterdiameter than that of the shaft and adapted to been gaged by a rope or cable belt.

In testimony that I claim the foregoing as ,my own I have hereto 'affixed my signature in the presence of two witnesses.

ANTON A. PETERSON.
